Perimeter is the sum of all the 4 sides:
Perimeter = L + L + W + W
Given Width = 10 and Perimeter = 68
L + L + 10 + 10 = 68
2L + 20 = 68
2L = 68 - 20
2L = 48
L = 48 ÷ 2 = 24
Length = 24 inches

Answer:
∠R= 110°, ∠U= 70°, ∠T= 110°
Step-by-step explanation:
Since, RSTU is a parallelogram, therefore using the properties of parallelogram, ∠S=∠U= 70° ( Opposite angles of parallelogram are equal).
Using the property, sum of adjacent angles is equal to 180°, therefore,
⇒∠S+∠R= 180°
⇒70°+∠R= 180°
⇒∠R= 180°- 70°
⇒∠R=110°
Also, ∠R= ∠T= 110° (Opposite angles of parallelogram are equal).
Thus, ∠R=110°, ∠T= 110° and ∠U=70°
Answer:
Step-by-step explanation:
Volume = length * width * height
= (x + 1) *x *(3x + 5)
Multiply (x +1) and x
= (x*x + x*1) * (3x +5)
= ( x² + x) * (3x + 5)
= x²*(3x +5 ) + x(3x +5)
=x²*3x + x²*5 + x*3x + x*5
= 3x³ + 5x² + 3x² + 5x
= 3x³ + 8x² + 5x
